LIDA F. BREWER, OF TOMS CREEK, VIRGINIA.

WIRE-TWISTER.

Application filed July 19, 1918.

To all whom 2'2. may concern:

Be it known that I, LIDA F. BREWER, a citizen of the United States, residing at Toms Creek, in the county of Wise and State of Virginia, have invented certain new and useful Improvements in Wire-Twisters, of which the following is a specification.

The present invention relates to improvements in wire twisters, or tools or implements for splicing, or coiling one wire about another, the device of the invention being particularly applicable for holding or twist- .ing trolley wires of electric railways.

The primary object of the invention is the provision of a tool that is simple both in construction and operation, that is composed of comparatively few parts, that is durable, and Withal, is efficient in performing the functions required of a tool of this character. One of the meritorious features of the invention is the facility and rapidity with which the tool may be applied to the wire to be twisted, or with equal facility be disengaged from the wire after having performed the required functions.

The invention consists essentially in certain novel combinations and arrangements of parts whereby the two pivoted jaws of thetool are locked or unlocked through the instrumentality of a spring pressed slidable locking tongue that engages the movable jaw, as will be hereinafter pointed out in the specification and claim.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of the invention, constructed and arranged according to the best mode so far devised for the practical application of the principles of the invention.

Figure 1 is a top plan view of a tool constructed accordin to the present invention and embodying t e novel features thereof.

Fig. 2 is a side view of the device.

Fig. 3 is a side view of a portion of the tool, the openable jaw bein open and the locking tongue and block belng omitted for convenience of illustration.

Fig. 4 is a side view of the locking memher for openable jaw of the device.

In the preferred embodiment of the in vention as depicted in the drawings, the tool includes a relatively fixed jaw 1, preferably of metal of the proper size and proportions Specification of Letters Patent.

Serial No. 245,661.

for a hand tool, and fashioned with a han dle portion 2 by means of which it may be manipulated. In conjunction with the relatively fixed jaw 1, an openable jaw 3 is utilized, the fixed jaw being cut away at 4: to accommodate the openable jaw, which is pivoted at the end of the fixed jaw to swing outwardly therefrom on the pivot bolt 5. The adjacent faces of the two jaws are provided with recesses 6 and 6 respectively which register and form cylindrical transverse openings through the tool to accommodate the wire or wires to be twisted or coiled. The wires are first laid in the recesses 6, with the jaw 3 open, and then the jaw 3 is turned back to position shown in Figs. 1 and 2 to incase the wires.

To hold or look the pivoted jaw in closed position, which is its normal position, I employ a tongue 7 formed at the top of the slide block 8, which is of metal, rectangular in shape, and of a size to slidably fit in a recess 9 extending vertically through the jaw 1. The slot is longer than the block in order that the block may slide, and to guide the sliding movement of the block, apair of trunnions or guide pins 11 are laterally projected from the block and extend outwardly through the side slots 10, 10 in the jaw 1, which open to the central slot 9. By means of the lug or boss 12 on the top of the slide tongue it is apparent that the block may be slid within the slots, guided by the trunnions, and the tongue 7 may be projected over the jaw 3 or withdrawn from the jaw to lock or unlock the jaw, and to hold the tongue in normally locked position I employ a protractile spring 13 seated in the socket 13 of the jaw 1 and at the other end seated in a socket 14 in one end of the block 8. Thus with the tool grasped in one hand, the locking member may be operated in ordcr that the openable jaw may with facility and despatch be actuated as required, and when the wires are properly positioned and retained in the jaws the tool may be turned in well known manner about the wires to coil or twist them one on another.

From the above description taken in connection with the drawings it is evident that I have provided a tool or device which fulfils the conditions set forth as the purpose of my invention.

What I claim is:

In a tool as described, the combination with a fixed and a pivoted jaw the former having a central vertical slot and lateral 5 slots in the side Walls of the vertical slot, of, a spring pressed block movable in the central slot and having trunnions slidably supported in the lateral slots, and said block having a retaining tongue normally eXtending over the free end of the pivoted jaw. 10

In testimony whereof I afiix my signature.
